How did the Sports Illustrated swimsuit model manage to upset Brown's passionate fanbase? With this tweet: "So excited to see Chris Brown! I love loud and surprising background fits of rage I can hear from the audience!"

A quick perusal of Teigen's Twitter feed reveals that a multitude of Brown's fans were enraged by her jokey comment and sent her an assortment of obscenity-laden, negative and just plain malicious tweets. The inflammatory nature of the messages reached a saturation point Tuesday (May 22) when Chris Brown himself took to Twitter to issue a cease-and-desist to his fans.

"Personally, I don't think @chrissyteigen's existence is pointless. Nor anyone else who dares criticize a performance. ...Every artist has to be ok with the fact that some people won't like their work. All critics aren't 'haters,' " he continued, aiming that last bit at Brown. "And don't ever tell me to put my 'bitch on a leash,' " he added, referencing the hateful messages he also received from angry Brown fans. "She's a grown woman with her own mind and her own opinions and this is not 1950."
